Letters Patent No. 110,305, dated December 20,1870,

IMPROVEMENT IN .COOKING-STOVES.

The Schedule referred to in these Letters Patent and making part of-thesame.

We, DAVID STUART and Lnwrs BRIDGE, both of Philadelphia, county ofPhiladelphia, State of .Pennsylvania, have invented an Improvement inCooking- St'oves, of which the following is a specification;

Nature and Object of the Intention.

Our invention relates to certain improvements in the cooking-stove forwhich Letters Patent were granted to our assignees, Stuart, Peterson &00.,-

Description of the Accompanying Drawing.

Figure 1 is a sectional perspective view of our im proved' cook-stoveFigure 2, a plan view Figure 3, a perspective View of part of the rearof the stove; and

Figures 4 and 5, views of detached portions of the stove. 4

General Description.

A is the fire-place of the stove, to which fuel is admitted through theusual opening a, in front, I) being the grate, and

B, the hearth-plate.

D is the large oven;

E, the small oven of the stove; G being a plate sit uated above thefire-place, and providedwith suitable holes for receiving culinaryutensils.

The back of the fire-place consists of an inclined plate, (I, the upperportion 01' which is made horizontal, and is so arranged as to bemidway, or thereabout, between the plate G and the top of the large ovenD, between which oven and the said plate (I is formed a flue, e, passingdownward and communicating with the horizontal fiuef, between the bottomof the-oven and bottom plate of the stove.

- At the rear of the oven is a hollow projection, F, formed by thecurved plate g and horizontal plate h, which has two openings forreceiving culinary utensils.

So far the stove is-similar to that for which the aforesaid LettersPatent were granted to our said which can be fitted aplate, M, fig. 4,having lips, in w, for fitting into slots in a flange, w, on the stove,the plate having at its lower edge a lip, y, fitting into the opening Mat the rear of the stove.

\Vhen the plate M is fitted to its place, the rear of the stove isequivalent to that of an ordinary stove but this plate maybe removed andh'ollowprojection, F, fig. 5, which has lips like those of the plate M,may be fitted to the opening M, at the rear of the stove, when thelatter will assume the form seen in fig. 1.

This changing of the stove from one having a plain back to one havingthe projection F may be etfected in the patterns, which, may be soconstructed that the back plate will be cast plain 01' with the hollowprojection F.

Within this projection is a plate, 1), on which rests a sliding damper,1 by moving the latter to the position shown in fig. 1, the products ofcombustion from the flue f may be made to pass outward and returnbetween the plate It and the plate 11, to the rear fluej, between theback plate 6 and the ovens.

On sliding the damper outward, however, the communication between thelower flue f and rear flue j will be direct.

This rear flue'j will communicate directly with the exit-opening F, ifthe sliding damper t, on the top of the upper oven, be moved inward; butthe communication between the rear flue j and exit-opening wui be cutoffif the damper be moved outward.

In the fine immediately behind the .firc-place is a damper-,1, which mayrest on the top of the lower oven, as shown, or may be turned so thatits edge will rest against the lower frontcorner of the oven, as shownby dotted lines, in which case the products of combustion will passupward through the flue m of the upper oven, and through the fine n tothe exit-opening, while, if the damper x be depressed,

part of the products of combustion will pass between the two ovens.

In fact, it will be seen, without further description, that bymanipulating the dampers x, t, and y,

the products of combustion may be directed to any part of the stovewhich circumstances may suggest.

-lo prevent dust and ashes or particles of fuel from passing over theend of the plate d, I secure to the same a serrated guard 16, seen infig. '1, and should any particlps pass this guard they are preventedfrom falling into and obstructing the fine 0 by a similar guard, is,secured to the upper front corner of the oven 1).

It will be seen that the guards k and It donot project entirely acrossthe lines, and therefore do not obstruct or interfere-with thepassage'of g'ascs through the'flues; that they are so constructed as notto be burnt out or injured by the heated gases, are inexpensive, and canbe readily applied.

' Claims.

.1. The plates of the stove, the half-plate, i, and

projection 1 adapted to each other,,as described, so

that the said half-plate and projection may be fitted to the stove, ordetached from the same and replaced by a whole plate, as set forth.

2. The guard 70, consisting of projections extending upward from therear of the plate 11, as described.
